Abstract: All-solid thin-layer batteries having materials used for electrolyte layers are stable in contact with anodes and cathodes in order to improve the operation and lifetime of the batteries. The materials used for the electrolyte layers do not enable the formation of metallic lithium precipitates, or internal resistance at the interfaces with the electrodes.

Abstract: A method for manufacturing an electrode having a porosity of between 20% and 60% by volume and pores with an average diameter of less than 50 nm. In the method, provision is made of a substrate and a colloidal suspension of aggregates or agglomerates of monodisperse primary nanoparticles of an active electrode material, having an average primary diameter D50 of between 2 and 100 nm, the aggregates or agglomerates having an average diameter D50 of between 50 nm and 300 nm. A layer is deposited from said colloidal suspension on the substrate. The deposited layer is then dried and consolidated to obtain a mesoporous layer. A coating of an electronically conductive material is then deposited on and inside the pores of the porous layer. Such a porous electrode can be used in lithium-ion microbatteries.

Abstract: Battery including at least one unit cell formed by an anode, an electrolyte, and a cathode, defining a stack. The stack of the battery has a plurality of faces that includes two end faces opposite one another, two lateral faces opposite one another, and two longitudinal faces opposite one another. The first longitudinal face includes at least one anode connection zone and a second longitudinal face of the battery includes at least one cathode connection zone that is laterally opposite to the at least one anode connection zone. In a first longitudinal direction of the battery, each anode current-collecting substrate protrudes from each anode layer, from each layer of electrolyte material or layer of a separator impregnated with an electrolyte, from each cathode layer and from each cathode current-collecting substrate layer. In a second longitudinal direction of the battery that is opposite to the first longitudinal direction, each cathode current-collecting substrate protrudes from each anode layer, from each layer of electrolyte material, or layer of a separator impregnated with an electrolyte, from each cathode layer and from each anode current-collecting substrate layer.
